COMBINED FANN INjG -MIL L AND cooKLE-sEPAR Toa- SPECIFICATION forming part of Letters Patent No. 317,412, dated May 5,

Application filed December 19, 1884. (No model.)

To all whom it may concern.-

of Michigan, have invented certain new and useful lmprovementsin Combined Fanning- I Mills and Cockle-Separators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon,

to receive the largest-sized cockle, but not which form a part of this specification.

My invention has for its object'to provide an improved novel and simplified construcof my complete invention; Fig. 2, a transverse section of the same, taken on the line .r of

Fig.1. Fig. 3 represents an end view, and

Fig. 4 a detail sectional view above the cockle- 1 rollers.

Similar letters of reference occurring on the several figures indicate corresponding parts.

Referring. to the drawings, A represents the main frame of my improved apparatus, which is provided at one end with a suitable fanchamber, B, and upon the top with a suitable hopper, (l, as shown, said hopper being pro- 1 vided with the slide a,'to regulate the flow of grain to the screens.

D represents the pulley, which, connected by the belt I) to pulley B, communicates mo tion to the fan E in the chamber B in the usual manner.

F represents the first or upper screen, to which the grain is delivered from the hopper G, and which is located above the slanting dead-bottom or conductor F.

G represents the next succeeding screen, lo

cated above the dead-bottom or conductor G,

and H represents the last or bottom screen,

all of said screens slanting to the open end of the machine, while the dead-bottoms or conductors slant toward the interior central por- Be it known that I, ELNATHAN PnELPs,'a tion of the same, as fully shown in Fig. 1. All

citizen of the United States, residing at Hartof the screens are vibratedf by meansof the ford, in the county of Van Buren and State I crank-arm I, projecting from the crank-shaft nally-arranged inclined rollers K, which are prefer ably constructed of heavy sheetiron, having a series of small depressions or hollows upon their entire surfaces, which are adapted large enough to receive the kernels of wheat.

Between the two rollers K is arranged an inclined distributing-board, g, having a sharp and raised center, so as to press the wheat to the faces of the rollers until the cockle is taken up by the depressions in said rollers and discharged into the chamber J beneath, while the clean grain passes down the inclined distributing-board g and is discharged through the spout K. The cockle is discharged from the chamber J through the spout J, by means of the spiral con veyer L, in a manner well known. The rollers K are revolved by means of the 1 gear-wheels M M, through the medium of the bevelgear N, which meshes with a similar gear, N, upon the shaft h of the pulley 0, said pulley 0 being connected by a suitable belt, 11,

to the pulley j upon the main driving-shaft d.

The spiral conveyer L is revolved by means of the spur-wheel It, actuated by the endless chain 1 upon the same and upon the gear-wheel M, as fully shown in Fig. 3.

In the operation of my invention the wheat or other grain first passes down from the hopper 0 upon the first screen, F, which carries over all straw or coarse matter, the grain falling through said screen upon the inclined deadbottom or conductor E, where it is subjected to a blast through the valve m, which carries away all fine dust, the blast being regulated by said valve to suit different kinds of grain. The grain next falls in a thin sheet upon the screen G, meeting with a stronger blast through the valve 11, which is regulated according to the grain handled. From screen G the grain drops down upon the dead-bottom or conductor G, which carries it back to the blast from valve 0, at which point both of the valves n and 0 are so regulated that both blasts can be brought to bear-on the grain in itstransitfrom screen removing all heavier foreign matter that has I not already been carried off. From the con-.' doctor G the grain is carried in a thin sheet;

to screen H, at which point the wilve 0 may be regulated to conduct another blast to the 3 moving grain.

The grain from the screen H is delivered into the hopperf, thence to the;

distributing-board 9, between the two rollers 1 K, the cockle being; taken up by the depressions in said rollers auddischarged from the machine, the cleaned grain passing down the distributing-board g, and out of the dischargespout K, as already above first described.

pressions in the face of the rollers said scrapp i ers would dislodge the grain and throw it back G tothe dead-bottom or conductor G, thereby upon the distributing-board g.

Having thus described the construction and operation of m y invention, 1 claim as new and useful- The herein-described combined fanning-mill and cockle-separator, comprising the frame A, provided with the fan-chamber B, fan E, hopper C, screens F, G, and H, conductors F G, valves m, n, and 0', hopper f, rollers K, distributiugboard g, conveyer L, and the gearwheels and driving-pulleys, substantially as and for the purpose specified.

in testimony whereof I afiix my signature l in presence of two witnesses.
